Answer:
a = 2
b = 3
c = 2³ or 8
Step-by-step explanation:
Exponent Rule: 
log₂(4) = 2 or 2² = 4
2⁵/2² = 2³
2³ = 8
your answer would be -2.57142857143
The answer is (inches/min)* (1ft/12in)
The function rule for x is +1. When you want to get the next number in the set, you add one to the previous number. For example, -1 + 1 = 0.
The function rule for y is - 5. When you want to get the next number in the set, you subtract five to the previous number. For example, 9 - 5 = 4.
Hope this helps!
